Nuclear Meltdown Relocation and Core Catcher Analysis
Vetor, 2023 Nuclear meltdown with the potential human and environmental harm is one of the major accident hazard (MAH) faced by nuclear power plants. Limiting (or entirely avoiding) criticality events are the main design strategies for reactors of generations 3½ ...

Numerical simulation on heat transfer of VVER core cather
He jishu, 2023 BackgroundThe core corium may melt through the reactor pressure vessel wall then lead to the failure of the second barrier during a serious accident. Core catcher can collect and cool the corium and prevent the development of severe accident.PurposeThis ...

Model for core catcher ablation and cavity shape in the film regime
Nuclear Engineering and Design, 2023 During core meltdown in a nuclear reactor the corium may propagates toward the lower and hit the vessel or structural elements as a coherent liquid jet. This could occur for instance in sodium fast reactors (SFR) if discharge tubes and an in-vessel core-catcher are used as mitigation devices.

Mud systems applied to problematic formations in core drilling rigs
Bulletin of the Mineral Research and Exploration, 2022 The two most important features of drilling rigs based on the core drilling principles are the drill set rotating at high speeds and the very precise spacing between the pipe and the well wall.
